    SQL CLR User Defined Types and Operator Overloading

    • 0 Comments

    Just talked with Shaun Hayward. Someone who onviously very passionate about coding. A (long) while ago he asked me for my opinion on Operator Overloading for User Defined types in SQL Server 2005.

    Shaun

          Good day 

          I came across your blog while looking for Yukon UDT info. 
          I've found that I can't deploy an assembly if any of my UDT's have overloaded the = operator. 
          I think this is strange since the SQL code would make a lot of sense: 

          SELECT MyTable.PlaceName FROM MyTable 
          WHERE MyTable.GPSCoordinateField='49.25,17.36' 

          Just wondering if you have any thoughts. 
          - Shaun

    Me

       I just found this email underneath whole lot of others. I’m really sorry for the really late reply.

       What you suggest would definitely make the code more esthetic. I’m not sure whether there are any other benefits since all can be achieved by writing a method on the UDT or by actually instantiating a    second    object and comparing them. In any case I can understand why the product chose not to invest in Operator Overloading. 

       Also, Operator Overloading does seem to be more challenging in an environment where you would use .NET code to overload a SQL operator. The ‘=’ in this statement is still a SQL Operator, agree?

    Shaun :-)

    Hi Hans 

    Thanks for the reply.

    We could get into a big philosophical debate about whether or not the “=” is really a SQL operator. I mean, what is an operator but a shortcut for calling a function? I could be wrong, but my guess is that .NET compiles = in VB.NET to one of those funky “op_” methods. Most operators seem to do this.  

    After all, everything (property, method, constructor, operator, or event) is just a method call in disguise. For that matter, .NET in general should be able to support custom operator defining. But I digress…

    The problem is that SQL Server has certain expectations for its operators. How can you ensure that hack developers actually do the right thing with an operator? What if they toss code into an endless loop? What if they call unmanaged code and throw an IPF or GPF? 

    So I fully appreciate why SQL Server cannot support them at this time. I suspect, however, that future incarnations will come up with ways to handle all of these problems and an operator will be neither a .NET operator nor a SQL Operator. .NET is blurring these lines, much to the praise of developers – myself included.

    For now, there is a work around by my philosophy of idealism remains much the same :-) 

    Once we have full operator control in SQL Server next then my next task shall be to elect an honest politician!

    One last way to get your session into TechEd Europe 2005

    • 0 Comments

    Surely, by now you have reviewed all sessions we've got lined up for TechEd Europe at our 80% list complete point. (http://www.mseventseurope.com/TechEd/05/Pre/Content/sessionsearch.aspx)

    Now let's say you really want to see another topic covered but you know that we closed the call for papers site on the 11th of March. What can you do?

    Like last year we are again having a room where we don't schedule the sessions but 'the community' does.

    For developer related topics 'the community' is INETA and the enthusiast managing the session list for that room is Damir Tomicic. He is looking forward to getting your ideas as you can read here: http://tomicic.de/PermaLink.aspx?guid=5566ef11-3237-446d-8c90-08673ef50d41

    The sessions 'the community' schedules are called Birds Of  Feather sessions. Allthough I don't really get that Bird thing, the sessions are really cool! They are allabout having a discussion around a specific topic. People flock together and share opinions and experiences. They are way more interactive than the regular TechEd sessions where most interaction is defered to the end.
     
    I'm hoping to see many great ideas coming from you, 'the community'.

    New SQL Server 2005 webcasts for developers

    • 0 Comments

    With these, I won't have to travel around anymore talking about Yukon :-) It's a win win!

     

    Discover how Microsoft SQL Server 2005 offers database developers the optimal combination of a tightly integrated development and data management platform. The rich and flexible programming environment in SQL Server 2005 allows you to leverage your existing skills and utilize familiar tools to build robust, secure, scalable applications.

    Register today to learn how the integration of the .NET Framework in SQL Server 2005 provides several major benefits, such as an enhanced programming model, enhanced safety and security, user defined types and aggregates, and a common development environment that integrates database development into the Microsoft Visual Studio 2005 development environment. In this series, we cover:

    • .NET Framework Integration: Learn how you can now take full advantage of the Microsoft .NET Framework class library and modern programming languages to implement functionality within the server.
    • Transact-SQL and Managed Code: Find out how to decide between using traditional Transact-SQL or a programming language that is compatible with the .NET Framework, such as Visual Basic .NET or C#. Understand where each method provides benefits and how to design for this in the beginning.
    • Web Services: See how to develop XML Web services in the database tier, making SQL Server an HTTP listener.
    • XML: SQL Server 2005 contains deep native support for XML. Learn how this can significantly help as you develop applications that make use of XML.
    • Data Access: Discover how ADO.NET 2.0 not only supports all of the new SQL Server 2005 features but also enables productivity and performance gains for all developers.
